CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit and priority of Chinese patent application No. 202121782245.6, filed on Aug. 2, 2021, disclosure of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present application relates to the field of insole, in particular to a foot arch, an insole and a shoe with a correcting function.

BACKGROUND

Under normal circumstances, the soles of human feet are arched, not flat. In medicine, this kind of arch is “built” together by three ridges, which are divided into two longitudinal arches in the front and rear directions and a transverse arch in the inner and outer directions. Informally, the foot arch is like a brick, which forms an arched bridge under the action of cement (ligaments and muscles), that is, the above-mentioned longitudinal and transverse arches. The outer arch shape is not obvious, but it actually exists. It just disappears when the load is loaded, which is called the lateral longitudinal arch. Viewed from the front and rear direction, there is also an arch that connects the inner and outer longitudinal arches, which is called the transverse arch. The three arches play a role in buffering vibrations; thereby protecting the plantar nerve blood vessels from compression and other aspects. The so-called flat foot is a kind of foot deformity, informally, is “solid feet”, that is, the above-mentioned arches become flat or disappears due to various reasons. When standing and walking, the arches collapse, and the soles of the feet become flat, resulting in fatigue or pain.

With the continuous improvement of the quality of life, people have higher requirements for the quality of life and are more willing to spend more energy on correction of flat foot disease. For example, the requirements for shoes and insoles are getting higher and higher, and people's requirements for insoles are not only limited to comfort. Currently in the prior art, the structure of the lower end surface of the insole or sole used for correction is single, and for the above-mentioned morbid flat foot phenomenon, an arched structure is formed by increasing the thickness of the insole or sole. However, due to the increase in thickness, unexpected phenomena such as wrinkling of the feet may occur during use, and the correction effect is insufficient.
